Letter from Sir David Bruce, Entebbe, Uganda, to Sir Michael Foster of the Malaria Committee Informs Foster of his research with Castellani. Notes that 70% of their examined cases contain trypanosoma -- thinks this is significant. Notes that 'the streptococcus is no longer believed in by Castelleni [sic]. I have helped him write a Note on this discovery'. Thinks that it will be a notable discovery if trypanosoma turns out to be the cause of sleeping sickness. Has sent a 'white man' with trypanosoma home with Castellani for Bradford to study. Hopes that Dr Manson 'will not indulge in after-dinner speeches anything I may write to the Committee'. Has been told by Castellani that G C Low advised him not to wait for Bruce's arrival. Other issues relating to equipment and the investigation. p41. 5 April 1903
